Add GCD cluster profile

[rochacbruno]

Summary

• Register ClusterProfileGCD ("gcd") for Google Cloud Dedicated
• Maps to cluster type "gcp" (reuses existing GCP cloud type)
• Lease type: "gcd-quota-slice"
• Added to LeaseTypeFromClusterType for template-based test compatibility

Context

This is part of CORS-4508: setting up Workload Identity Federation authentication for the OpenShift installer on Google Cloud Dedicated (Berlin environment).

The corresponding openshift/release PR will add the cluster profile config, Boskos quota slices, secret bootstrap entry, and installer CI job configuration.

Generated with Claude Code

Summary

This PR adds support for Google Cloud Dedicated (GCD) cluster infrastructure to the OpenShift CI tooling. The changes introduce a new cluster profile gcd that maps to the existing GCP cloud provider implementation, allowing CI jobs to target GCD clusters without duplicating provider logic.

Changes

pkg/api/clusterprofile.go:

• Added a new ClusterProfileGCD constant with value "gcd" to register the GCD cluster profile
• Included the new profile in the ClusterProfiles() enumeration function
• Mapped the profile to use the same GCP cloud type (CloudGCP) as other GCP-based profiles
• Associated a gcd-quota-slice lease type with the profile
• Updated the LeaseTypeFromClusterType() mapping to recognize the "gcd" cluster type and resolve it to the corresponding gcd-quota-slice lease type

Impact

This enables the CI infrastructure to provision and manage test clusters on Google Cloud Dedicated infrastructure. The new cluster profile reuses the existing GCP cloud provider implementation while establishing a distinct identity for GCD resources. This is part of implementing Workload Identity Federation authentication for the OpenShift installer on GCD, specifically targeting the Berlin environment (CORS-4508).

Corresponding configuration is being added to the openshift/release repository, including cluster profile configuration, Boskos quota slice definitions, secret bootstrap entries, and CI job configuration.

This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

📝 Walkthrough

Walkthrough

Adds a new exported constant ClusterProfileGCD = "gcd" to pkg/api/clusterprofile.go and wires it into four places: the ClusterProfiles() enumeration slice, the ClusterType() switch (mapping to CloudGCP), the LeaseType() switch (returning "gcd-quota-slice"), and the LeaseTypeFromClusterType accepted-type set.

ClusterProfileGCD constant and full wiring pkg/api/clusterprofile.go	Declares ClusterProfileGCD ClusterProfile = "gcd", includes it in ClusterProfiles(), maps it to CloudGCP in ClusterType(), returns "gcd-quota-slice" from LeaseType(), and adds "gcd" to the accepted set in LeaseTypeFromClusterType.

Stable And Deterministic Test Names	✅ Passed	PR only adds cluster profile constant and configuration mappings in clusterprofile.go; no Ginkgo test definitions are added or modified, so the test name stability check does not apply.
Test Structure And Quality	✅ Passed	PR contains no Ginkgo test code changes—only cluster profile constant definitions and mapping logic in clusterprofile.go, making test structure review inapplicable.
Microshift Test Compatibility	✅ Passed	PR adds cluster profile configuration only; no new Ginkgo e2e tests are added, making the MicroShift test compatibility check inapplicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The custom check applies only to new Ginkgo e2e tests. This PR adds only a ClusterProfileGCD constant and mapping logic with no tests, so the check is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	PR only adds a cluster profile constant and enumeration mappings to pkg/api/clusterprofile.go; does not introduce deployment manifests, operator code, controllers, or any scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	PR adds only constant and switch statement mappings with no process-level code or stdout writes that could violate OTE binary stdout contract.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR adds only a cluster profile constant and API mappings in clusterprofile.go; no Ginkgo e2e tests are added, so the IPv6/disconnected compatibility check does not apply.
No-Weak-Crypto	✅ Passed	PR adds cluster profile configuration mapping only; no cryptographic operations, algorithms, or secret comparisons are introduced.
